Abstract
The percentages of combined closely trimmed and semi-boneless lean of fattening culled dairy carcass were classified into five yield grades, 1 through 5. Yield grade 1 carcasses had the highest semi-boneless lean percentage more than 81 % and yield grade 5, the lowest percentagde which combined in closely trimmed semi-boneless lean was less than 68. A significant regression equation was found (F = 13.321, p < 0.05), with an R2 of 0.305. The equation for predicting the combined in closely trimmed and semi-boneless lean percentage of fattening culled dairy carcass is combined in closely trimmed and semi-boneless lean percentage was 81.523 – 0.851 (marbling score, 1-5) – 1.209 (rib fat thickness, cm.) – 0.097 (chest cavity width, cm.) + 0.060 (rib-eye area, square cm.) + 1.302 (sex, 0=male, 1=female).
